I have some extra information. If I open a file and save it as V7, it shows the file thumbnail when I go back to open it immediately afterward. However, if I open another file and save it the thumbnail for the previously opened file reverts back to just a file icon. No idea what’s going on.
If it’s any help, my file thumbnails still work for SolidWorks, so I don’t believe it’s a Windows setting.
Been playing around with this again to try and resolve. Have some additional information. When I copy a Rhino file from one folder to another folder, the pasted file in the new folder will create a thumbnail image.
However, this is only temporary and after a while it reverts back to just a file icon.
To make things even more confusing, files that are copied to my desktop do have a thumbnail image, but that seems to be the only location that this is true for.
Hi Mark - and files saved from V6 show the thumbnail, is that correct?
Somehow this feels kinda-maybe like an installer thing, possibly; I’ll start with that developer. @Mark_Landsaat - are you running Rhino at the same permission level as Windows? Not using ‘run as administraor’ or something? not likely, I know, just making sure there is nothing non-standard there.
Hi Mark - the thumbnails are also missing if you use Rhino’s File > open and browse around? not just in independent Explorer windows? I think so, just making sure…
And of course… have you rebooted?
One more thing - a bit of a long shot but one never knows, one of my colleagues has found it helps in apparently related cases: testRestoreLibraryFileAssociations
Yes, thumbnails are also missing when I use Rhino’s File>Open.
Just ran the testRestoreLibraryFileAssociations command and this required a restart. But also had restarted several times after I changed settings.
When I activate the preview pane in Rhino’s File>Open I do get a thumbnail preview of the file. Unfortunately none of this is helping so far.
Have we reached the point where I uninstall V7 and reinstall? Not sure if it would change anything, but it doesn’t seem like we have very many options left.
So am I, just to show I’m not making this up, I copied a few files to my desktop see screenshot. And for good measure, a screenshot of a folder with Rhino files in it. The uninstall/reinstall will have to wait for now. I will let you know how that works out, hopefully later today. Thanks.
Did the uninstall/install, but unfortunately still no luck. Something weird is going on. Check out the screenshot, they show my recently opened files and these do have a thumbnail preview. However the same files in their actual file location only shows the Rhino file icon. I’m at a loss of what to try next.
Appreciate the help. Only one PC, but files are backed up to OneDrive. I can disable OneDrive to see if it makes a difference.
Nothing weird about dark mode, just changed color settings in applications, or use dark mode if available in application.
Things were working fine in Rhino 6. I don’t know what’s different, but obviously something has changed. Also didn’t think this was a universal problem, but whatever is triggering this may also be an issue for other users.
Are you familiar with the Sysinternal tools (downloadable from Microsoft)? You could run the process monitor (procmon), filtering to include events with thumbcache or iconcache in the path over an interval where you expect to see a thumbnail revert to an icon and then see what processes are accessing the various cache databases. Might give some insight into what is going on.
